LEGO Technic - 13 studs axle with diff-lock

The present video shows a 13 studs Lego Technic axle with suspension, steering and diff-lock which fits for most of the Lego Technic wheels. The diff-lock works pneumatically. Enjoy the video!

"Optimed steering linkage"Also adds ackermann steering, which is nice

[@functionalTechnic]

yes, it is a wellcome side benefit. Therefore, the steering linkage needs alwas to be placed behind the axle.

[@simonechiarlo919]

fantastic! I can not wait to try to implement these axles in a vehicle😃👍

[@functionalTechnic]

I'm glad you like it. Feel free to use it

[@andrewcollins6525]

thats awesome!

[@reducki]

You have done a wonderful job This is amazing!

[@functionalTechnic]

Thanks alot.

[@lc-jrx]

Very nice and complex axle. Well done!

[@functionalTechnic]

Thanks. Your Zetros does also have 13 Studs axles or 15 studs?

[@lc-jrx]

The way you count my front axle is 11 stud wide. The rear axle is 13 studs wide. As I use planetary gears I need one stud less than with the wheel hubs.

[@quinsey8655]

Wow! Great work! 😺 Your design skills are truly impressive. You do excellent work in creating your videos too. Thanks tons for sharing here with us! 👏

[@functionalTechnic]

I'm glad you like it. you can also find some ldd files on my webpage

[@Nico71Fr]

Nice and interesting design :)

[@functionalTechnic]

thanks

[@antoineddpLEGOTechnic]

WOW well done ! Very good stering system !

[@functionalTechnic]

thanks

[@chrismolenr]

Good suspension idea!

[@functionalTechnic]

thanks, it works well but it needs a lot of space. For big tires its is fine, for small one the suspesnsion is to large. but the axle can also be used without supension

[@henningrehm4725]

Great Job

[@functionalTechnic]

thanks

[@michanowacki9152]

Super:)

[@crispinshipp2624]

i liked your vids so much i subscribed

[@functionalTechnic]

thanks

[@legomasterbuilder9118]

I loooooove the compactness and the mechanical look to it. Awesome creation!! I might use it in some build if you don’t mind

[@functionalTechnic]

i'm glad you like it. you can use it for your model. But, there are no instructions available for this axle

[@legomasterbuilder9118]

functional Technic surprisingly enough, I was able to recreate it completely just from this video . Now I’m thinking about how to make the suspensions and connect the steering and drive to a motor

[@pangniadek]

Awesome ;)

[@functionalTechnic]

thanks

[@chrismolenr]

Cool!

[@functionalTechnic]

thanks

[@legomasterbuilder9118]

After building it, I can tell it is very good. Everything works really well. Only hard thing is getting good suspension on the front axle, but that I can figure it out

[@functionalTechnic]

I'm glad you like it. What about the short yellow springs?

[@legomasterbuilder9118]

functional Technic yeah that works but it’s making good linkages and getting both axles for drive and steering to the middle of chassis that I struggle with.

[@CapricornRichCat]

cool😎

[@carldavey1]

This is such a great design. I hope you don't mind but I have prepared instructions and a parts list for these axles and submitted them on Rebrickable. I have passed on credit by linking back to this video and to your channel.

[@functionalTechnic]

Hi, thats fine. Good work.

[@ivantrgovac1906]

Awsome design and idea for differential lock. I just wish it was bigger.

[@functionalTechnic]

how big? make it bigger is not a problem.

[@ivantrgovac1906]

@@functionalTechnic I don't know in which scale is this differential 1:10, 1:9 or something else, but I prefer 1:8 scale or even bigger like 1:6 scale of the real car. I'm curently building a lamborghini aventador 1:6 scale ( 80cm long) and I'm excited to see it drive since I'm testing the endurance of technic pieces. So this design of yours can be tremendously helpful and be used as a parking brake to lock the differential of a car so it doesn't move while being placed uphill or downhill. :)

[@p3l1k44n1]

I need a suspension for a similar sized axle but i dont have those rubber bushings..

[@functionalTechnic]

guess you can get it from lego directly or over bricklink for sure

[@schokielyas7077]

Very Nice! Can I habe The Building Constitution to build it also

[@functionalTechnic]

Hi, there are no building instructions. Maybe you can do it with the video. I took also some pictures, which I will place one my webpage soon

[@anexer2229]

Good job! Any plans for using them in a model?

[@functionalTechnic]

Hi, thanks. There was a concept for a truck but it didn't work. I wanted to build an amphibious craft but the truck faild but not the axles. Therefore, I shared them here and rebuilt the amphibious craft with new axles. the present model does have idependend suspension also with diff-lock. I hope that it will work this time

[@anexer2229]

@@functionalTechnic i think these axles in the video would suit a mercedes unimog

[@functionalTechnic]

yes, probably with the 94mm LEGO Technic tires or to a Mercedes Zetros with Custom 80mm tires

[@LathanT16]

Could you fit big yellow hard springs on it ???

[@functionalTechnic]

sure. Instructions you can find on rebrickable. There will follow a similar axle on my rebrickable account. But not earlier than next spring

[@Martin-xb2rz]

With portal axles

[@functionalTechnic]

This axle doesn't have protal axles but maybe you can add some

[@tomaskvasnovsky5827]

Hello, please send me instructions?Tahnk you

[@functionalTechnic]

I don't habe instructions but an other guy made some: rebrickable.com/mocs/MOC-38966/carldavey1/13-stud-front-rear-axles-with-diff-lock/#info

[@TechnoFishlego]

Instructions please 🙏😁

[@functionalTechnic]

you should find some on rebrickable: rebrickable.com/mocs/MOC-38966/carldavey1/13-stud-front-rear-axles-with-diff-lock/?inventory=1#comments

[@user-vb5tz7pj9h]

How can build it

[@functionalTechnic]

rebrickable.com/mocs/MOC-38966/moc_cupboard/13-stud-front-rear-axles-with-diff-lock/#details

[@matthewskincat1961]

Very good and compact, but sadly I don't have air pistons...

[@functionalTechnic]

Thanks. You can get them on bricklink.com. But, if you build the axle without suspension, then you can make the diff-lock also with a linear actuator or another linkage

[@technicbricks2146]

Directions?

[@functionalTechnic]

what do you mean?

[@technicbricks2146]

Sorry, I ment are there PDF instructions

[@functionalTechnic]

not from me but you can find it here: rebrickable.com/mocs/MOC-38966/moc_cupboard/13-stud-front-rear-axles-with-diff-lock/#details
